Hi,

I am creating object for each device and then connecting the devices as below.

C#

int iNoOfPunchStation = int.Parse(System.Configuration.ConfigurationSettings.AppSettings["NoOfPunchStation"]);
            for (int i = 0; i < oPunchStation.Length; i++)
            {

                oPunchStation[i] = new zkemkeeper.CZKEMClass();
                bIsConnected = oPunchStation[i].Connect_Net(System.Configuration.ConfigurationSettings.AppSettings["Station" + (i + 1)], Convert.ToInt32("4370"));
                if (bIsConnected == true)
                {
                    if (oPunchStation[i].RegEvent(1, 65535))//Here you can register the realtime events that you want to be triggered(the parameters 65535 means registering all)
                    {

                        oPunchStation[i].OnKeyPress += new zkemkeeper._IZKEMEvents_OnKeyPressEventHandler(axCZKEM1_OnKeyPress);
                        oPunchStation[i].OnHIDNum += new zkemkeeper._IZKEMEvents_OnHIDNumEventHandler(axCZKEM1_OnHIDNum);

                    }
                }
            }

my doubt is. I want to identify the device from which the data coming in event name 'axCZKEM1_OnHIDNum'
that is, which punching device?

the event 'axCZKEM1_OnHIDNum' as below.

C#

private void axCZKEM1_OnHIDNum(int iCardNumber)
       {
          
       }

no idea.. :(

Thanks..

Where is 'axCZKEM1_OnHIDNum' implemented: in the Class definition for 'zkemkeeper.CZKEMClass ?

zkemkeeper.CZKEMClass class have
[TypeLibType(16)]
[ComVisible(false)]
public delegate void _IZKEMEvents_OnHIDNumEventHandler(int CardNumber);

then I implemented.

You can pass the event source via closure. First change your event handler signature to this:

C#

private void axCZKEM1_OnHIDNum(zkemkeeper.CZKEMClass oPunchStation, int iCardNumber)

And register the handler like this:

C#

oPunchStation[i].OnHIDNum += x => axCZKEM1_OnHIDNum(oPunchStation[i], x);

I assumed zkemkeeper.CZKEMClass (oPunchStation) represents the device. So where is the device id hidden then?

Thank you sir. now working . but passing ip address of device instead of object and make a single object.

thank you sir...thanks a lotss..
